Saturday Nov 22, 2008 (foodconsumer.org) -- A new review study suggests that many years of research with animals and clinical trials are needed to assess the safety of genetically modified foods.

The review found most studies indicate that GM foods may cause some common toxic effects such as hepatic, pancreatic, renal, or reproductive effects and may alter the hematological, biochemical and immunologic functions.  

Animal toxicity studies have already shown that GM foods may toxically influence organs and systems.

The authors also say that the use of recombinant GH or its expression in animals should be re-evaluated since it has been found to increases IGF-1 which may promote cancer.

The review was conducted by Dona A and Arvanitoyannis IS from the University of Athens Medical School in Athens, Greece and published in the Feb 2009 issue of Critical Review of Food Science and Nutrition.

The most common GM foods used in the US include corn, canola and soybean.
